Abstract: The present disclosure includes optical articles comprising a film layer that has first and second film surfaces and is embossed such that the first film surface defines a plurality of concave optical elements and the second film surface defines a plurality of convex optical elements. The present optical articles can include one or more optical layers coupled to the film layer. Each of the optical layer(s) can encapsulate the concave optical elements or the convex optical elements.

Abstract: A film structure including at least a functional film, a carrier layer, and a counter-force liner, the functional film being in between the carrier layer and the counter-force liner. The carrier layer and the counter-force liner are larger than the receiving area, and the film structure includes a fastener adapted to fasten, directly or indirectly, the counter-force liner to the carrier layer at least on a portion of a zone outside the functional film. It is also proposed a corresponding machine, optical device and method for forming a functional film intended to be laminated on an optical article.

Abstract: Disclosed is a lamination machine including: a film support for receiving a functional film to be laminated; an article support configured to receive and position the optical article in a predetermined orientation; and an actuating member configured to move the film support and the article support toward each other for laminating at a predetermined pressure the functional film received in the film support onto the optical article received within the article support. The article support is a blocker support configured to receive a surfacing blocker onto which the optical article is to be disposed for lamination, the article support being further configured to transmit laminating forces induced by the predetermined pressure to the lamination machine during a lamination operation.

Abstract: Disclosed is a semi-finished lens that includes a blank formed in a first material having a first hardness, the blank having an outline, a first face and a second face configured to be surfaced so as to constitute a first optical face of the ophthalmic lens, and a top layer formed in a second material having a second hardness greater than the first hardness, the top layer having an outline, a first face and a second face, the second face of the top layer being arranged on the first face of the blank. The outline of the top layer is equal to or included in the outline of the blank, and satisfies to a predetermined dimensional selection criterion involving the final outline of the ophthalmic lens.

Abstract: A laminated optical lens having an edging-optimized laminar configuration and method for manufacturing same. The laminated optical lens includes an optical base lens and a film layered structure including an external film furthest from said lens. An adhesive layered structure is placed between the film layered structure and the optical base lens so as to permanently retain the film layered structure on the surface of the optical base lens. The laminated lens is manufactured by laminating a film layered structure having an external film to an optical base element with an adhesive layered structure. The external film has a thickness of at least 100 μιπ, and preferably a thickness in the range of 150 microns to 300 microns inclusive. The adhesive layered structure has a thickness in the range of 5 microns to 100 microns inclusive, and preferably of 25 microns to 50 microns inclusive
